OSGI vs other frameworks

I started going through OSGI at later stage of my career and then I am wondering why did I spent learning Struts vs Spring vs Seam. I could have learnt OSGI and keep it using from last 10 years. The framework is cloud agnostic from day one. Thanks Kirk for promoting OSGI concepts further.

This post makes no sense. If you intended it to be ironic then you missed adding a few smilies to go along with it. If you really think that OSGi is any way comparable to Spring/Struts/Seam then you haven't understood it at all.
